Thanks for your work on it, even if it resulted in a regression. :)

I don't quite understand why that would be the issue here; guix system
reconfigure works fine when /dev/mmcblkN is specified target in the
system config.scm, just not when the target is /dev/disk/by-id/...
My wild guess was something was checking for a literal block device, and
failing with a symlink pointing to a block device.
Trying your patch gets me a backtrace, unfortunately...
With the bootloader section...
(bootloader (bootloader-configuration
(target "/dev/disk/by-id/mmc-SDU64_0xbaf3002e")
(bootloader u-boot-pinebook-bootloader)
))
And your patch applied on top of 3e09453884efa82ef97b8ec6e34470c67a1206a7...

It also fails when target is /dev/mmcblk1.
So, clearly this is some other issue...
